We run on an RCP track http://www.hircr.com/ so I dont know how much help I can give. Our track might be a little tighter than what yall run on. The trick on our track is to keep the weight of the car down as much as possible. An extra ounce makes a HUGE difference. Most of us are are running the Motek 140mm chassis. The reason is it never tweaks, its light and the shorter wheelbase allows the car to pivot better like Bobby Z is saying. When I say pivot, its like the front to rear is nuetral and theres this imaginary point in the car, hopefully near the center that it "Rotates" on during cornering. If you have push or not enough steering, you lose.

We have a problem with steering on our track. We have too much steering. We have so much traction that we lock down the front end. I mean, no suspension travel at all. And we loosen up the rear as much as possible. We never use Paragon on the front tires.

Bearings are an issue with XRay. If you havent upgraded bearings yet, you need to do so. I love XRay, but their bearings suck!

Ball diffs are a must! As is a Spectrum pro micro receiver.
